Abstract (en)

[origin: WO9848294A1] A positioning system locates a mobile unit by compensating for component tolerances in time-of-arrivals of received signals at a plurality of positioning radio receivers. The system determines detection times of the received radio signals at the positioning radio receivers. The system takes into account pre-stored signal delays associated with one or more receiver stages of the corresponding positioning radio receivers and the detection times, for determining time-of-arrivals for the received radio signals.
